STOVE-LID.

Specification of Letters Patent.

Patented Mar. 15, 1910.

Application filed May 22, 1909. Serial No. 497,577.

To all whom it may concern:

Be it known that we, BENJMEN F. GILL and JOHN D. KIZER, citizens of theUnited States, residing at Scranton, in the county of Lackawanna, Stateof Pennsylvania, have invented certain new and useful Improvements inStove-Lids; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable `othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in stove lids, of the classwherein provision is made for increasing and accelerating thecombustion, and controlling the supply of heated air to a stove.

The improved device is applicable more particularly to cook stoves, andfor the purpose of illustration is shown applied to a griddle or coverof this character.

The principal obj ect of the invention is to improve the constructionand increase the efficiency and utility of devices of this charaeter.

lith these and other objects in view, the invention consists in certainnovel features of construction as hereafter shown and de scribed andthen specifically pointed out in the claim, and in drawings illustrativeof the preferred embodiment of the invention, Figure 1 is a plan view ofthe improved device. Fig. 2 is a section on the line 2 2 of Fig. 1.Fig'B is a section on the line 3 3 of F ig. 1. Fig. 4 is a plan view ofthe base member detached. Fig. 5 is a bottom plan view of the uppermember detached.

The improved device is formed in two parts, a base portion comprising anannular rim 10 and a depressed central portion 11, whereby a relativelylarge circular recess 12 is formed. The annular member 10 is providedwith an annular shoulder or ledge 13, and bearing upon this shoulder orledge is the upper member 14. The upper member is secured to the lowermember by a plurality of screws 15 or other suitable fastening devices.The lower member'll is provided with a small inclosed chamber 16, andthe upper member 14 is provided with an aperture 17, the aperture being`somewhat smaller than the chamber, and coacting with the chamber toproduce an eliicient cavity for the reception of the stove lifter. Bythis means the two connected parts 14-11 may be placed in position uponthe stove or removed therefrom in the ordinary manner.

The central portion 11 of the base member is provided near its outerside with a plurality of spaced apertures 18, leaving the centralportion without the apertures, shown in Fig. 4.

The upper' member 14 is provided centrally with a sunken portion 19, andmounted for rotation in this sunken portion 19 is a plate 20, the lattersecured in position by a screw 23. The depressed portion 19 is providedwith a plurality of spaced apertures'21, and the plate 20 is providedwith a corresponding number of apertures 22, the apertures 22 equalingin number the apertures 21. Vhen the plate 2O is disposed in oneposition the apertures 21-22 will be in registering position, and whenthe plate 2O is disposed in another position the apertures 22 will comeopposite the solid portion of the depressed portion 19, and thus out offthe supply of air passing through the chamber 12.

The apertures 21-22 being located centrally of the plate 14, and theapertures 18 being located near the outer portion of the base member 11,the air which enters through the apertures 21-22 when the latter arearranged in registering position must necessarily pass laterally toenter the apertures 1S, and any air which passes rst through theapertures 18 must pass toward the center and escape through theapertures 21--22 By this arrangement it will be obvious that the air iscaused to take a somewhat circuitous route, and in its passage throughthe device is heated to a high degree before it enters the combustionchamber, it being understood that any inequality of air pressure withoutand within the combustion chamber respectively causes the air to feedautomatically through the conduit passages just described.

The improved device is simple in construction, can be inexpensivelymanufactured, and adapted without structural changes to stoves ofvarious sizes, and to stoves employing various kinds of fuel.

What is claimed is The herein described stove lid comprising a basemember having an upwardly extending rim formed with an annular shoulderon its inner side and an outwardly extending annular supporting flangeon its outer side, said base member being further provided withperforations in its bottom near its periphery; an upper plate supportedon the said annular shoulder, spaced by said rim from the bottom of thebase member and provided with a circular depressed eentral portion, thebottom of Which is provided with perforations, said plate being' furtherprovided with a lifter opening and said base member havinga ehamberedportion under said lifter opening and on which the said plate bears,means securing the base member and the plate together, and a euto'Pfplate mounted for rotation in the depressed central portion of thefirst-named plate and having perforations to be brought into or out oregister with those of the bottom of said central depressed portion.

In testimony whereof, We affix our signatures in presence of twoWitnesses.
